Authenticate an SSH Tunnel with a Private Key

Demonstrates Socket.SshAuthenticatePk, which authenticates an SSH tunnel session using a private key loaded into an SshKey object. Call SshOpenTunnel first.

The file path is relative to the application's current working directory. An absolute path may also be used. Supply the path appropriate to your own environment.

Background. The SSH server must have the corresponding public key authorized for the account. If the private key is encrypted, set the SshKey.Password property before loading it.
